摘要：

The electroproduction of rho mesons with proton diffractive dissociation for Q(2) > 7 GeV2 and the elastic electroproduction of phi mesons for Q(2) > 6 GeV2 are studied in e(+)p collisions at HERA with the H1 detector, for an integrated luminosity of 2.8 pb(-1). The dependence of the cross sections on P-t(2) and Q(2) is measured, and the vector meson polarisation obtained. The cross section ratio between proton dissociative and elastic production of rho mesons is measured and discussed in the framework of the factorisation hypothesis of diffractive vertices. The ratio of the elastic cross section for phi and rho meson production is investigated as a function of Q(2).
